TRUSS.

SPECIFICATION forming part of Letters Patent No. 461,039, dated October 13, 1891.

Application tiled April 25, 1891. Serial No. 390,460. (No modeld To all whom it may concern:

Be it known that I, ANTON NAIDL, a citizen of the United States, residing at Omaha, in the county of Douglas and State of Nebraska, have invented certain new and useful Improvements in Trusses for the Treatment of Hernia; and I hereby declare the following to bea full, clear, and exact description of the same, reference beinghad to the aceompanying drawigns, in Which- Figure 1 is a perspective view of a truss embodying my invention. Fig. 2 is a central section of the same?. Fig. 3 is a detail sectional View of the rocking post and its socket, and Fig. 4 is a transverse section of the sectional ball-joint on the line @c Fig. 2.

Like symbols refer to like parts wherever they occur.

My invention relates to the construction of adjustable springball or spring-pad trusses for the treatment of hernia; and has for its object to simplify the adjustment of the post and ball and render effective and secure the relative position of said parts after the adjustment thereof.

To this end the main feature of myinven vention, generally stated, embraces the conlbination, with the post, of a sectional clampbearing and clamp-socket, whereby the post may be pushed in or drawn out to increase or diminish the pressure and may be set and secured at any desired inclination to the pad.

There are other minor features of invention, all as will hereinafter more fully appear.

I will now proceed to describe my invention more fully, so that others skilled in the art. to which itappertaius may apply the same.

In the drawings, A indicates a portion of the belt or body-band which supports the trusspad,and in the presentinstance is shown as of wire, preferably annealed, so as to render it capable of being bent to vary the position of the truss pad or ball. The portions of the truss-bandA which are not shown may be attened and leather-covered in the wellknown manner of forming body-bands for trusses. As this'belt embodies no feature of the present invention, any well-known form of belt may be substituted therefor.

B indicates the ball or pad provided with a central well h for the reception of the spring l, which spring` supports the post-socket and permits a yieldingr endwisc movement of the post to relieve the wearer of the truss from the rigid pressure of the truss liable to pr0- duce bad results. This well h also provides forthe en dwise adjustment of the post through its socket.

2 indicates the truss-plate, whichis secured to the ball in any suitable manner and is provided with a central opening for thereception of the post-socket, said opening preierably being of suliicient size to permit the free movement of the postsocket in the plate.

3 indicates thepost-socket, which is preferbly composed of two horizontal flanged sleevesections 3 3b, held together by threaded bolts 4 4, which pass through the truss-plate 2, though another form of sectional post-socket and connections may be employed, if desired. I, however, prefer the construction shown, as the screw-bolts 4 4 not only serve as guides to prevent the side mot-ion or cramping ofthe socket in the plate, but also as means for drawing the section of the socket together to clamp the post-joint and secure the post. The upper and under edges of the socket-sections may be beveled or countersunk, as at c, to permit the post to be inclined in any desired direction, and the under face of the socket 3 may be grooved, as at d, to form a seat for the end of spring 1.

5 indicates the clamp-bearing of the post. This bearing is composed of sections 5a 5b, tbc., (see Fig. 4,) corresponding` in shape, as a whole, to the interior of post-socket 3, and provided with a central cavityor hole for the passage of the post G. Bytnrning the screw bolts 4 4 to loosen the sections of post-socket 3 the post 6 may be moved through this clampbearing to increase or diminish the distance between the pad and belt, after which the bolts 4 4 maybe tightened up to cause the clamp-bearing to bind on and hold the post.

In addition to the before-specified adjust ment of the post as to its length, it is desirable to adjust its inclination to the pad, and to accomplish this I prefer to form this clampbearing 5 in the form of a sectional ball and the interior of the post-socket 3 in the form of a cup, as shown in the drawings, to obtain a ball-and-socket or universal joint, so that IOO the post can be set at any desired inclination to the pad by the same operation, and at the same timeits length is adjusted. l

The inner end of the post 6 may be provided With a button '7, and its outer end can be secured to a suitable clamp-plate 8, Whioh @lamp-plate 8, in conjunction with clampyoke 9 and serews l0 and Il or equivalent means, may be employed for adjustably rsecuring the post 6 to the belt or body-band A.

Among the advantages of my invention are simplicity of construction, combined With facility in adj usiment and security ot' the parts when adjusted.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

l. In a truss, the combination, with a truss ball or pad, of a sectional clam p-post socket, sectional elamp-post bearing, and a post adj ustable through the sectional clamp-bearing, substantially as and for the purposes speciiied.

2. In a truss, the eombination,with the ball or pad, of a ball-aud-soeket bearing for the post, and a post adjustable through the said j in presence of two Witnesses, this 18th day of 35 April, 1891.
